See the filter at first glance good. The courses could be a bit softer but that can not be seen in the photo or video. Filters sit tight in the filter holder and can be moved hard. It could be a bit more relaxed sitting position. But rather than fixed on the floor and broke.
More I can not say unfortunately. Suitable for wide-angle 11mm less. Here the manufacturer could improve and make the filter holder a little wider. But of course, the glass filter.
Delivery fast and as always went without problems.
